Cold chain

A cold chain is a type of special supply chain that helps keep things cold. It's like a regular supply chain but it has extra steps to keep things chilled. The cold chain starts at a special refrigerator and freezer where items are stored at a very cold temperature. Then, special trucks are used to transport the items to their destination, where the temperature is carefully monitored to make sure nothing spoils or melts. Finally, once the items reach their destination, a special cold storage is used to maintain the temperature until the items are used. So, a cold chain helps keep food, medicine, and other items cold so that they are kept safe and don't spoil or melt during transportation.
